К вопросу применения нестабилизированного напряжения в системе электропитания космического аппарата

In this article the spacecraft load voltage stabilization range influence on the specific power parameters (W/kg) of the power system as a complex of the electric power supply system and the secondary power supply devices (DC-DC convertors) built in loads is considered. It is showed that the secondary power supply devices usage in the on-board equipment on the base of a flyback impulse convertor for the load voltage of (25–27) V allows providing for the higher specific parameters than for the load voltage of (17–36) V within the range of loads up to 3 kW. The graphic characteristics and analytic formulae are derived
